5.9.2 With active ”safe standstill” function
ƒ Only qualified personnel are permitted to install and set up the “Safe
standstill” function.
ƒ All safety-relevant cables (e. g. control cable for the safety relay,
feedback contact) outside the control cabinet must be protected, for
instance, by a cable duct. Short circuits between the single cables must
be ruled out!
ƒ Wiring of the safety relay K
SR
with insulated wire end ferrules or rigid
cables is absolutely vital.
ƒ The electrical reference point for the coil of the safety relay K
SR
must be
connected with the protective conductor system (DIN EN 60204-1
paragraph 9.4.3). Only this measure guarantees that the operation is
protected against earth faults.
Tip!
A complete description of the ”Safe standstill” function can be
